- WVMED .specification of Letters rant no. 28,713, aatd Janas;

To aZZ whom 'it may concern:

Be it known that LJosnrH Cleveland, county of Cuyahoga, Vand StateofrOhio, have inventedza newzand useful Improvement i-n Hose-Gouplings;and I do`` hereby declare that the followingis afull, clear, and -exactdescription thereof,i reference being had to` the aocompanying draw-``ngs, forming a part of this specification,` in which- .i ,i

Figure 1, represents a top View of my imiproved hose coupling,`with the1male and` female parts connected andlockedsecurely together. Fig. 2, isa central longitudinal section taken vertically throughthe coupling whenthe joint is formed, and lyng in the position represented by Fig. 1.T-'he female part of this coupling is represented detached from the malepart, and in a positionto form a junction of the two.`

Similar letters of reference indicate `correspondingparts in bothfigures.

This invention is an improvement in hosecouplings for fire engines andother purposes, the object of which is, to enable the connection anddisconnection to be made with a strong head of water fiowing through thehose, thus enabling the firemen to make a connection without stoppingthe engine,

which, with the present style of hose-coupling, must be done.Inconjunction with the facility of ooupling and uncoupling, a perfectjoint is formed, and securely locked, so that there will be no liabilityof the conpling getting accidentally detached by handling. The screw isdispensed with and the couplings can be made cheaper than the presentscrew couplings, while they are Very com-' pact and light. They are notso liable to derangement, and will not be materially affected by snow,ice or Sand, which are sometimes very serions evils to the screwcoupling.

My invention consists in forming a connection and looking the male andfemale portions of the coupling together, by peculiarly appliedeccentric levers, described and represented as follows.

To enable those skilled in the art, tofully understand my invention, Iwill proceed to describe its construction and operation.

In the drawings, A, represents the male part and B, the female part ofthe coupling, the hose being attached to the necks of these by any ofthe usual methods, the jointof this coupling is Very similar to theordinary i Josnrn SINGER; or' oLnrv'irLAND,` ciao. mi

The most important feature of my invention is, the manner of tighteningup the joint, should it become leaky through constant use; this iseifected by Cutting screwthreads on the small half of the coupling,oorresponding with a thread on the inside of the ring, D, and when thejoint becomes loose, the ring may be moved back sufliciently to permitthe eccentric arms to aot upon the fiange of the female half of thecoupling, so as to draw the two halves more tightly together.

For making a connection with this improved coupler, the eccentric leversare thrown as far as they will go, shown by red lines Fig. 2; the faceof the female coupling is then set fair on the face of the male coup-'ling and'slid together with a slight down- Ward pressure, until thefemale part drops down over the male butt, so that its face will abutagainst the india rubber packing as in Fig. 2. The eccentric levers arethen thrown c it will be forward, and depressed as in Figs. 1 and 2 andthe parts are forcibly compressed and a perfect water and air tightconnection is obtained. The uncoupling is efected as easily as thecoupling, the operation requiring only to be' reversed.

I do not wish to confine myself to the use of this coul ling exclusivelyto fire-hose, for ound applicable and useful for many other purposes;and by employing three eccentric levers, the coupling will be found Veryserviceable for the suction-pipes of fire-engines; and for many otherVsimilar purposes I contemplate using my improved side coupling.

Having' thus described the Vessential features ,of my invention what Iclaim, and desire to secure by Letters Patent, is:

The adjustable ring D,'arms, E, E, and I eccentric levers F, F, incombination with the semi-circular strip G, allV applied and op eratingin the manner and for the purposes herein set forth. i
